INDEMNIFICATION, COSTS AND EXPENSES

Section 7.01 Indemnification by EEP. EEP agrees to indemnify the Purchaser, its Affiliates and their officers, directors, members, managers, employees and agents (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), whether or not involving a Third Party Claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by EEP contained herein to be true and correct in all material respects as of the date hereof (except with respect to any provisions including the word “material” or words of similar import, with respect to which such representations and warranties must have been true and correct) or (ii) the breach of any of the covenants of EEP contained herein; provided, that in the case of the immediately preceding clause (i), such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a Purchaser Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to EEP shall constitute the date upon which such claim has been made; provided, further, that the liability of EEP shall not be greater in amount than the Purchase Price.

Section 7.02 Indemnification by the Purchaser. The Purchaser agrees to indemnify EEP, its Affiliates and their officers, directors, members, managers, employees and agents (collectively, “EEP Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), whether or not involving a Third Party Claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by the Purchaser contained herein to be true and correct in all material respects as of the date hereof or (ii) the breach of any of the covenants of the Purchaser contained herein; provided, that in the case of the immediately preceding clause (i), such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a EEP Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to the Purchaser shall constitute the date upon which such claim has been made; provided, further, that the liability of the Purchaser (and its Affiliates, if the Purchaser transfers a portion or all of the Purchased Units to an Affiliate) shall not be greater in amount than the Purchase Price.

Section 7.03 Indemnification Procedure.

(a) A claim for indemnification for any matter not involving a Third Party Claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification that it may claim in accordance with this Article VII, except as otherwise provided in Sections 7.01 and 7.02.

(b) Promptly after any EEP Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement (each, a “Third Party Claim”), the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such Third Party Claim but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such Third Party Claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle such Third Party Claim, it shall promptly, and in no event later than five (5) days, notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and/or the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying

14

Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has, within ten (10) Business Days of when the Indemnified Party provides written notice of a Third Party Claim, failed (y) to assume the defense or settlement of such Third Party Claim and employ counsel and (z) notify the Indemnified Party of such assumption, or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such settlement or legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not contain any admission of wrongdoing by, the Indemnified Party.

Section 7.04 Tax Matters. All indemnification payments under this Article VII shall be adjustments to the Purchase Price, except as otherwise required by applicable Law.

Regardless of any purported general termination of this Agreement, the provisions of Article VII and all indemnification rights and obligations of EEP and the Purchaser thereunder, and this Article VIII shall remain operative and in full force and effect as between EEP and the Purchaser, unless EEP and the Purchaser execute a writing that expressly (with specific references to the applicable Section or subsection of this Agreement) terminates such rights and obligations as between EEP and the Purchaser.

Section 8.03 No Waiver; Modifications in Writing.

(a) Delay. No failure or delay on the part of any party in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise.

(b) Specific Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification or termination of any provision of this Agreement shall be effective unless signed by each of the parties hereto or thereto affected by such amendment, waiver, consent, modification or termination. Any amendment, supplement or modification of or to any provision

16

of this Agreement, any waiver of any provision of this Agreement and any consent to any departure by EEP from the terms of any provision of this Agreement shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on EEP in any case shall entitle EEP to any other or further notice or demand in similar or other circumstances.

Section 8.04 Binding Effect; Assignment.

(a) Binding Effect. This Agreement shall be binding upon EEP, the Purchaser and their respective successors and permitted assigns. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and permitted assigns.

(b) Assignment of Rights. The Purchaser’s rights and obligations hereunder (including the right to seek indemnification) may be transferred or assigned in whole or in part by the Purchaser to any Affiliate of the Purchaser without the consent of EEP. Upon any such permitted transfer or assignment, references in this Agreement to the Purchaser (as they apply to the transferor or assignor, as the case may be) shall thereafter apply to such transferee or assignee of the Purchaser unless the context otherwise requires. No portion of the rights and obligations of EEP under this Agreement may be transferred or assigned without the prior written consent of the Purchaser, which consent shall not be unreasonably withheld.

Section 8.05 Communications. All notices and demands provided for hereunder shall be in writing and shall be given by hand delivery, electronic mail, registered or certified mail, return receipt requested, regular mail, facsimile or air courier guaranteeing overnight delivery to the following addresses:

Section 8.06 Removal of Legend.

(a) The Purchaser may request EEP to remove the legend set forth in Section 4.05(e) from the certificates evidencing the Purchased Units by submitting to EEP such certificates, together with an opinion of counsel to the effect that such legend is no longer required under the Securities Act or applicable state laws as the case may be, as EEP may request; provided, that, no opinion of counsel shall be required if the Purchaser is effecting a sale of Purchased Units pursuant to Rule 144 promulgated under the Securities Act or the Conversion Units have been registered under the Securities Act pursuant to an effective registration statement. EEP shall cooperate with the Purchaser to effect removal of such legend. Subject to the provisions of the EEP 5th Partnership Agreement, the legend described in Section 4.05(e) shall be removed and EEP shall issue a certificate without such legend to the holder of Purchased Units upon which it is stamped, if, unless otherwise required by state securities Laws, (i) such Purchased Units are sold pursuant to an effective registration statement, (ii) in connection with a sale, assignment or other transfer, such holder provides EEP with an opinion of a law firm reasonably acceptable to EEP, in a generally acceptable form, to the effect that such sale, assignment or transfer of such Purchased Units may be made without registration under the applicable requirements of the Securities Act, or (iii) in connection with a sale, assignment of or other transfer of such Purchased Units, such holder provides EEP with a representation letter that such Purchased Units will be sold, assigned or transferred pursuant to Rule 144 promulgated under the Securities Act. EEP shall bear all direct costs and expenses associated with the removal of a legend pursuant to this Section 8.06; provided, that the Purchaser shall be responsible for all legal fees and expenses of counsel incurred by the Purchaser with respect to matters addressed in this Section 8.06.

18

(b) Certificates evidencing Conversion Units shall not contain any legend (including the legend set forth in Section 4.05(e)), (i) while a registration statement covering the resale of such security is effective under the Securities Act and the Purchaser delivers to EEP a representation letter agreeing that such Conversion Units will be sold under such effective registration statement, (ii) following any sale of such Conversion Units pursuant to Rule 144 promulgated under the Securities Act, or (iii) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission).

Section 8.07 No Third Party Beneficiaries. Except as provided in Section 7.01 and Section 7.02, nothing in this Agreement shall provide any benefit to any third Person or entitle any third Person to any claim, cause of action, remedy or right of any kind, it being the intent of the parties that this Agreement shall otherwise not be construed as a third Person beneficiary contract.
